Inventor: KANEKO TOSHIHIKO
IPC: F28F19/01
Filed: 1985-12-23
Abstract: PURPOSE:To prevent the deterioration of performance of cooling tubes, caused by the blockade of them effected by foreign material, and the pollution of nature by a method wherein a foreign material removing device is provided at the entrance of a heat exchanger to take the foreign material out, introduce it into a foreign material retrieving device together with water accompanied by it to separate the foreign material from the water and the water is discharged through a water discharging pipe while the foreign material is disposed as industrial wastes. CONSTITUTION:Cooling water (sea water) passes through a screen 1, and the pressure thereof is increased by a cooling water circulating pump 2, thereafter, it passes through a water introducing pipe 3 and flows into a foreign material removing device 4. The foreign material is separated here and flows out of a system through the inlet port water chamber 6 of a multi-tube type heat exchanger 9, a cooling pipe 7, an outlet port water chamber 8 and an outlet pipe 10. When the separated foreign material 20 flows into a foreign material retrieving device 13 together with water accompanied by it, the foreign material 20 is separated from the water, then, the pressure of the water is increased by a pressure increasing pump 15 and the water joins with cooling water again through a pipeline 16. Accordingly, th blockade of cooling pipes for the heat exchanger, which is caused by the foreign material, may be reduced and nature pollution due to discharging the cooling water may be eliminated. The foreign material 20, thus retrieved, is disposed properly as industrial wastes.

Title: Steam dryness meter
Inventor: WATANABE KENICHI
IPC: G01N7/00
Filed: 1988-11-14
Abstract: PURPOSE:To make it possible to measure dryness accurately by keeping warm temperature around a dryness meter under a vacuum state. CONSTITUTION:A pressure P1 of a steam to be measured in a main steam pipe 1 is read with a pressure gage 8. A temperature T2 of overheated steam through a pressure reducing valve 3 after adiabatic expansion is read with a temperature sensor 5. Enthalpy I'1 of saturated water at a pressure P1 and enthalpy I''1 of saturated steam at the pressure P1 are obtained based on the read values, a saturated steam table and an overheated steam table. Enthalpy I2 of the overheated steam at a temperature T2 in a measuring container 4 and a preset pressure P2 at the pressure reducing valve 3 is obtained. Then, dryness X is obtained by X = (I2 - I'1)/(I''1 - I'1). Here, the pressure in the container 4 is reduced with a vacuum pump 6, and the temperature of the entire dryness meter is kept under a vacuum state. Thus, pressure decrease larger than reduction only with an orifice can be generated. Even in low pressure wet steam and steam whose dryness is low, there is no error due to heat radiation. Even if the steam pressure to be measured is fluctuated, the dryness can be measured accurately and simply.
